My post over at Nesting scenes is possible. What is it good for? got blocked when I tried to post a link from it to a GitHub repo. And now that thread is invisible!
When I tried to post a reply, it said something about “unable to link to that host” and I’m guessing that host was github dot com.
It seems a bit harsh of a rule for this Discourse instance to prevent posting github links (and making the whole thread invisible), because other github projects might be related to Three.js and people might like to share them. At worst, the thread shouldn’t be completely taken off, just the reply not allowed to post.
